Update to 1.20.2

[RubixDev]

Things that changed:

• updated to gradle 8.3
  • replaced classifier = "..." with archiveClassifier.set("...") in build.gradle files
• bumped mod version to 2.9.1
• updated all dependencies to their latest 1.20.2 versions
• mouseScrolled events now have a vertical and a horizontal scroll amount in Minecraft, overriding methods have been updated to reflect the added parameter
• Loot table serialization now uses Codecs instead of Gson directly in Minecraft, the code to send the loot tables to players has been changed appropriately
• The DataFixType.SAVE_DATA has been removed in Minecraft in favor of multiple more specific types. I semi-randomly picked SAVED_DATA_MAP_DATA to use for WorldGenState, but I have no clue what the best option is here. I guess we would maybe even have to add our own enum variant to DataFixType now using fabric-asm, but I'm really clueless about anything related to the DataFixerUpper.

closes #20

@RubixDev Do you know how hard it'd be to upgrade to 1.20.4 from your branch? Just upgrading versions/dependencies will work or minecraft internals changed?

@sarim sorry, I don't know and I'm not planning to. I personally use EMI with JER now anyways.
